52 is divisible by 4, so 452 is divisible by 4.
452 is even, so 452 is divisible by 4.
5 + 2 = 7 and 7 is not divisible by 4, so 452 is not divisible by 4.
4 + 5 + 2 = 11 and 11 is not divisible by 4, so 452 is not divisible by 4.
3 + 1 + 2 + 6 = 12 and 12 is divisible by 6, so 3,126 is divisible by 6.
26 is not divisible by 6, so 3,126 is not divisible by 6.
3,126 is even, so it is divisible by 2 and 3 + 1 + 2 + 6 = 12 and 12 is divisible by 3,
